9.25.2.4.(1)

Intent 1:

To limit the probability of installing loose-fill insulation in assemblies where the material is subject to:

• excessive settlement or displacement due to gravity and vibration,
• incomplete coverage, or
• moisture damage.

This is to limit the probability of compromised thermal resistance, which could lead to excessively low temperatures of interior surfaces or within assemblies.

This is to limit the probability of condensation, which could lead to deterioration, which could lead to compromised structural integrity of assemblies acting as environmental separators, which could lead to harm to persons.

Intent 2:

To facilitate the determination of compliance with this Code where fill levels of loose-fill insulation could be difficult to verify.
